o al who i may conc rn:

Be it known thatl, PEA L A. Baum, a citizen of the United States, andresident of Colfax, inthec'ounty ofJasper and State i love, h e i e t ceta n, n an user'ul Harrow Truck, of which the following'is'aspecification. i

The object of my inventionto provide a harrow and truck ofcomparativelysimple, durable and inexpensive construction."

Afurtlier'object is to provide a harrow of the type'having rotatableteeth carrying members, and in connection therewith 1. a'eliab e membersdapt to be e di y and easily mounted upon said teeth carrying membershaving thereon suitable runnersoii the like adapted to travel on groundand als su tablie e ie de ices."

More particularly it is my object to provide suc'han attachment of verysimple and inexpensive Construction which can be readily and easilyattached to anyordinary harrow or removedftherefrom without specialskill and with ordinary tools.

A further object isto provide such a device including an attachmenthaving runners or the like so arranged that a" pliiral sectionharrow maybe, moved oi er the ground on runnerswith the sections following eachother in succession instead of being ar' ranged side by side as whenthey are used for cultivation.

My invention consists in the construction, arrangement and combinationof the variou parts of the device whereby the objects. co n templa'tedare attained as hereinafter more fully set forth, pointed out in myclaim and illustrated in the accompanying drawings, in which:

'Fi gurel shows a top or plan view oia two section harrow equipped witha truck attachment embodying my invention.

Fig. 2 shows a side elevation of the same.

Fig. 3 shows a top or plan view of a portion of one of the teeth holdingmembers having my improved truck attachment secured thereto.

Fig. 4 shows a side elevation of the same, and

Fig. 5 shows a front elevation of the same.

In the illustration of my invention-shown in the accompanying drawings,I have used the reference numeral 10 to indicate gen- Specification ofLetters Patent.

Patented Oct. 23, 191? erally the fore-and-a ft longitudinal frame 11 11 9 73 of bar w whi h ar ata sr mounted the transverse teeth holdinginenhers 11 preferably made of tubing.

In the drawings Ihave shown two harrow sections which ll"? similar instructure. In the members 'l 1 are mounted harro i teeth 12 suitableway.I The harrow sections are arranged side side for use as shown in Figl. l

Secured to the frame member 10 by means of chains lg or other s uitablefiexibleda ices a long draw bar 14:.

Fe ro a e member '11, and h re y regulating the. angle of the teeth withrelation to the ground to be cultivated have secured to the members 1 1arms 15. arranged parallel with each' other and ex tending upwardly fromthe members-11.

Pivoted'to the upper ends of the arms 15 is a horizontal connecting bar16 arranged fQreend-aft in the machine and forwardly and rearwii dlyprojecting ends.

The, rear end or the connecting barl6 is pivotally securedto, a lever17, having an ordinary spring actuated pawl 18 adapted to coact with thesector 15;) mounted onftl e two rearward frame members ll 7 Theforwardly projecting portions. of the connectingbars" are bent to, forms itable receiving devices 20 for the draw bar 14,, so that' the drawbar may held in position restingiii the devicesj2O when desired[ r Myimproved truck attachment comprises four devices for each harrowSection. One of Stud dev ces will now 'descrlbe.

The upper portion of each truck attache de i celeri se own ard p rlug 26secured to the outer end of which a is a runner 9 7 or other suitabledevice for traveling on the ground. The adjacent flanges 23 of themembers 2:2 and 25 are secured together by means of bolts 28 and nuts 2lhe size of the members 22 and 25 is such that their edges do not quitetouch when they are installed on the member 11, so that the bolts 28 andnuts 29 may be used for drawing the flanges together for causing themember 11 to be very firmly gripped between the members 252 and 25.

in installing the truck attachment, the lever 1? is preferablymanipulated until the teeth 12 stand substantially in vertical position.The members 22 and 25 are then installed on the frame members 11 withthe lugs 26 lying in a horizontal plane and extending away from themembers 11 at right angles to the teeth. The lugs are so ar ranged thatwhen the lever 17 is moved in the proper direction the members 11 willthen be rotated bringing the teeth 12 to horizontal position, as shownin Fig. 2, while at the same time the lugs 26 are era In vertical.position where the runners or other suitable device 2? are rested uponthe surface of the ground.

t will be understood that I do not confine myself to the use of runners26, and intend to cover by my application any suitable device forcarrying the harrow sections over the ground.

In the practical use of my improved harrow truck, it will be seen thatthe harrow may be used in the field in the ordinary way without anyinterference from the truck attachment. When, however, it is desired todraw the harrow along the road for any considerable distance, themembers 11 may be rotated for bringing the runners 27 to positionresting on the ground.

The successive sections of the harrow are then secured together at theiradjacent encs by means of connecting rods 29 having at each end an eye30 adapted to receive one end of the heel: device The draw bar 14 isplaced in the members 20. Rods 31 having eyes 82 are arranged at one endof ground without interfering na iaoie the harrow and placed in positionwith the eyes 82 receiving the members 2% at that end.

The team may be hitched to the rods 3 in any suitable way.

It will be seen that by the arrangement just described the harrowsections can be drawn upon the runners 2'? over the hard with the roadand with a great reduction in the draft that would exist it the harrowsections had to be dragged on their teeth.

The change from the position 01"" the harrow sections where they travelupon their teeth to their position for traveling upon the truel;attachment can be made almost instantly.

0n account of the fact that the team is hitched at one end of the seriesor" harrow sections, and the further fact that the harrow sections aresecured together end to end, the harrow sections can be drawn along theground and the width of the harrow is then only equal to half of onesection.

This manes it possible to draw the harrow 3 which could not be doneotherwise without untastening the draw bar 141 and taking the harrowsections through one at a time or stacking them one above the other.

Many of the advantages of my improved truck attachment may be seen fromthe fore going explanation.

It is my intention to cover by my present application any such changesor modifications of structure of use of equivalents which may be.reasonably included within the scope of my claim.

1 claim as my invention:

in a device of the class described, a pair of oppositely openingchannel-shaped members having opposite adjacent ilanges,means forsecuring the flanges of the opposite members together, one oi saidchannelshaped members having on its outer surface an outwardlyprojecting engaging device, the other of said channel-shaped members having on its outer surface, an outwardly projecting lug, and a runner orthe like thereon.
